So let me see if I can schedule some time with the NDT and I will get back with you. Please send me a note off the reflector on the time frame you would like to have this meeting, and the time frame for the output from the NDT. I will set something up for you to present to the NDT. . . . John L.

Hello, The gateway "sub-group" has had a few discussions around node naming - and I thought I would see what the wider community thought about one of the ideas. Note that this issue doesn't concern the current iSCSI documents (which aren't attempting to address gateway issues) - so I definitely do not intend to de-rail their march to closure/last call! I'd like to gage people's reaction to having a form of the iSCSI node name for gateways. I think this idea was mentioned at Huntington Beach in reaction to Dave Petersen's presentation on portal groups. Dave's presentation suggested that two separate gateways presenting the same FC node could present a single node (with an "eui." name) with 2 portal groups. An alternative suggested was the gateways should present the FC node as two separate iSCSI nodes (so that each gateway would be an entirely separate I_T_nexus). One drawback of this alternative is that the configuration of the iSCSI network couldn't extend to the FC node but rather only to the gateway (for example, there'd be no way to have the FC node be a member of an iSNS discovery domain - only each individual gateway). An iSCSI node name format for gateways might be like the "eui." form - along the lines of "gw.nodeEUI64.gatewayEUI64". This could allow the separate node/I_T_nexus presentation as suggested but still provide a "handle" (the root "gw.nodeEUI64") to be configured for discovery (i.e. iSNS or SLP). Or - rather than a new "gw." form, maybe just an expanded "eui." form or an expanded "iqn." form by setting aside a specific URL (like iqn.2002-04.com.fciscsigateways.nodeEUI64.gatewayEUI64). Having a name format like this doesn't address some aspects (like setting a mode page on "gw.nodeEUI64#1.gatewayEUI64#1" might also effect "gw.nodeEUI64#1.gatewayEUI64#2"), but it could be helpful for configuration of discovery. All comments welcome. Regards, Rob Rob Grant McDATA Corporation
